  1. I2C for R-Car platforms
  2. Required properties:
  3. - compatible: Must be one of
  4. "renesas,i2c-rcar"
  5. "renesas,i2c-r8a7778"
  6. "renesas,i2c-r8a7779"
  7. "renesas,i2c-r8a7790"
  8. "renesas,i2c-r8a7791"
  9. "renesas,i2c-r8a7792"
  10. "renesas,i2c-r8a7793"
  11. "renesas,i2c-r8a7794"
  12. "renesas,i2c-r8a7795"
  13. - reg: physical base address of the controller and length of memory mapped
  14. region.
  15. - interrupts: interrupt specifier.
  16. Optional properties:
  17. - clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
  18. propoerty indicates the default frequency 100 kHz.
  19. - clocks: clock specifier.
  20. Examples :
  21. i2c0: i2c@e6508000 {
  22. #address-cells = <1>;
  23. #size-cells = <0>;
  24. compatible = "renesas,i2c-r8a7791";
  25. reg = <0 0xe6508000 0 0x40>;
  26. interrupts = <0 287 IRQ_TYPE_LEVEL_HIGH>;
  27. clocks = <&mstp9_clks R8A7791_CLK_I2C0>;
  28. clock-frequency = <400000>;
  29. };
